- Removed info about installation which is already covered in individual tool docs and has been unchanged for years
- Add considerations about resource limits, security permissions, container size, and attack surface
- Add information about the newer --diagnostic-port CLI option which doesn't require process namespace or /tmp sharing
- Add warnings that tools (dotnet-dump especially) could cause containers with insufficient memory to be killed.
- Warn that dotnet-dump writes out the dump relative to the target container file system view
- Remove the weird recommendation that suggested perfcollect was only intended for pre-.NET Core 3.0 apps.
- The text was unnecessarily refering to Docker. This guidance is likely to apply to any Linux container runtime, not just Docker.
